Should I put a waterproofer on the wood thats' not in contact with substrate?
Best thing to protect wood that touches substrate? FRP is hard to find by me and I don't have tools to cut it to the sizes.
Best way to connect plywood sheets together?
For the frame should I use screws or nails to secure it?
thanks

Ya, Wayne's link is great as it shows pictures and breaks it down really well.
In answer to your questions, I dont think it would be that much of an issue using either type of insulation. They both work well, so its just a matter of your preference. Fibreglass is pretty itchy, but foam is a little tougher to work with; both will do fine. As to how much you need, just ask your hardware store and they should be able to give you an estimate.
Its good to at least seal the wood above the substrate, yes. Its going to be high humidity in there all the time, so any exposed wood will rot. You can use just a simple water based deck sealant (polyurethane) for the top though if you want, as it wont be in contact with the substrate. For the bottom that is in contact with the substrate, use epoxy resin like they use on boat hulls, bar tops, etc. It dries hard and waterproof, and you just paint it on.
For the frame, in my opinion its always better to use screws rather than nails. You never know when you might have to take it apart again, or replace one part, so screws are the way to go.
What are you going to be putting in that nice new enclosure?
